Have you ever wondered why √ 4 is NOT plus or minus 2? Or is it more? Are you one of those who believe that it is +2 and -2? In this video, I explain where this common mistake comes from and how to avoid it. Through clear arguments and the use of a graph, you will understand why only +2 is the correct answer.
